​WinCon-205 is a color former for use in thermal paper.

WinCon-205 can be applied in the conventional way as a color former by the application of an aqueous coating composition to a pre-coated base paper followed by drying and calendaring. The coating composition will also contain appropriate amounts of various additives including for example color developer and sensitizer.
The performance of WinCon-2 will therefore be governed to some extent by the choice of the other coating components in the coating formulation as well as the quality of the base paper. A top coat may be applied on the thermal layer as a protective coating.


  • Suitable for almost all thermal paper grades
  • Excellent dynamic sensitivity
  • Good background stability
  • Good image stability
  • Can be used for blending to counter negative impact on Image stability when WinCon-2 is used in combination with Bisphenol A
